Instead of hardcoded knowledge of certain classes in MetaWindowGroup, create a generic interface that all actors can implement to get parts of their regions culled out during redraw, without needing any special knowledge of how to handle a specific actor. The names now are a bit suspect. MetaBackgroundGroup is a simple MetaCullable that knows how to cull children, and MetaWindowGroup is the "toplevel" cullable that computes the initial two regions. A future cleanup here could be to merge MetaWindowGroup / MetaBackgroundGroup so that we only have a generic MetaSimpleCullable, and move the "toplevel" cullability to be a MetaCullableToplevel. https://bugzilla.gnome.org/show_bug.cgi?id=714706
